Deno Deploy Has a Free Serverless Platform With Zero Config

#deno #serverless #typescript #deploy

Deploying a JavaScript/TypeScript server usually means: Dockerfile, build steps, CI pipeline, cloud config. Deno Deploy means: deployctl deploy.

Why Deno Deploy

Zero config — no Dockerfile, no build step, no bundler
Globally distributed — runs in 35+ regions
Instant deploys — under 2 seconds
Native TypeScript — no transpilation needed
Web standard APIs — fetch, Request, Response, crypto

Free Tier

1M requests/month
100 GiB data transfer/month
KV storage included
Custom domains + auto-SSL

Hello World

// main.ts
Deno.serve((req: Request) => {
  const url = new URL(req.url);

  if (url.pathname === "/api/hello") {
    return Response.json({
      message: "Hello from Deno Deploy!",
      timestamp: new Date().toISOString(),
    });
  }

  return new Response("Not Found", { status: 404 });
});

deployctl deploy --project=my-api main.ts
# Live at https://my-api.deno.dev in ~2 seconds

Deno KV (Built-in Database)

const kv = await Deno.openKv();

// Set
await kv.set(["users", "alice"], { name: "Alice", email: "alice@test.com" });

// Get
const entry = await kv.get(["users", "alice"]);
console.log(entry.value); // { name: "Alice", ... }

// List with prefix
const users = kv.list({ prefix: ["users"] });
for await (const entry of users) {
  console.log(entry.key, entry.value);
}

// Atomic transactions
await kv.atomic()
  .check({ key: ["users", "alice"], versionstamp: entry.versionstamp })
  .set(["users", "alice"], { ...entry.value, verified: true })
  .commit();

KV is globally replicated — reads are fast from anywhere.

Queues (Background Jobs)

const kv = await Deno.openKv();

// Enqueue a job
await kv.enqueue({ type: "send-email", to: "user@test.com", subject: "Welcome" });

// Process jobs
kv.listenQueue(async (msg) => {
  if (msg.type === "send-email") {
    await sendEmail(msg.to, msg.subject);
  }
});

Cron Jobs

Deno.cron("cleanup", "0 * * * *", async () => {
  const kv = await Deno.openKv();
  const old = kv.list({ prefix: ["sessions"] });
  for await (const entry of old) {
    if (isExpired(entry.value)) {
      await kv.delete(entry.key);
    }
  }
});

Built-in cron. No external scheduler needed.

Fresh Framework (Full-Stack on Deno Deploy)

deno run -A https://fresh.deno.dev my-app
cd my-app && deno task start

Fresh is Islands Architecture + Preact + file-based routing — perfect for Deno Deploy.

npm Compatibility

import express from "npm:express@4";
import { PrismaClient } from "npm:@prisma/client";
import Stripe from "npm:stripe";

Most npm packages work out of the box with npm: prefix.
